PPMS® DynaCool™ Cryogen-free Physical Property Measurement System
System availability: Summer 2010
Quantum Design announces that it has a new development project to produce a Pulse Tube Cryocooler-based version of its popular Physical Property Measurement System (PPMS). The concept of this new system, called the DynaCool™, will be to provide all the current capabilities of the PPMS without the need for any liquid cryogens.
The DynaCool system uses a two-stage Pulse Tube cooler to not only cool the superconducting magnet but also provide the cooling for the temperature control system and the internal thermal shield. Utilizing a new approach to cryocooler equipment design, the DynaCool system employs a new 4He-based temperature control system and gas flow technology. | |

The DynaCool will also incorporate an integrated CryoPump that can be used to pump the sample space to a vacuum of <10-4 Torr. This allows for the easy installation the various PPMS Measurement Options or user experiments that may require a high vacuum environment.
Features
 | No use of cryogenic liquids
|
| Fully automated operation of all PPMS applications/options
|
| Built-in Cryopump for high vacuum application
|
| New electronics using CAN architecture for improved reliability
|
| Standby mode conserves power and requires only 30 minutes to become fully operational
|
Benefits
| Avoids the cost and inconvenience associated with the use of liquid helium and liquid nitrogen
|
| System requires only electricity (7.5 kW), water and helium gas for operation
|
| Can be used even where no liquid helium is available and infrastructure
|
| Eliminates need for expensive helium reliquification equipment
|
| Can be operated only when measurements are needed |
